Foreword
In 1998, when Sunopsis first opened its door to begin development of the product that would
become ODI, the technology landscape was very different from today. There were very few
data warehouses over 10 terabytes, and both the underlying hardware and software were
struggling to keep up with the load and query demands placed upon them. As a result, the
warehouses only included the most critical transactional data from the few key systems. The
prevailing ETL approach of the day was to hand-build highly optimized flows, which executed
in dedicated hardware, and then spoon-feed the results into the data warehouse. In this
context, the founding principles of ODI were extraordinarily bold: leverage the data warehouse
itself as the transformation engine and enable developers to work at a much higher level of
abstraction, counting on the tool to generate an optimized execution plan.
Viewed with hindsight 15 years later, these principles seem prescient. Data warehouses have
grown to be petabytes in size, and the hardware that houses them is often the most powerful
in the data center — 100s of processor cores, terabytes of RAM, and 10s of terabytes of Flash.
After many years of concerted effort, and with thousands of mappings to show for it, many
enterprises have added far more transaction systems into their warehouses, and they are
now looking to bring in data sets that have hitherto been dark (for example, server logs, social

media feeds), and may be best preprocessed on open source distributed frameworks such as
Hadoop. The world has finally caught up to ODI.
Congratulations on your decision to take a different approach to bulk movement and
transformation of data within your business. For developers experienced on traditional ETL
tools, you will discover yourself doing far less mundane work once you grasp a few of the key
ODI concepts such as topologies, knowledge modules, and set-based transformation. This
book will be an excellent companion for you on this journey. Written by four experts on the
product (with decades of experience among them), including key product managers who are
continuing to drive ODI's evolution, this book complements the product documentation with
a variety of practical recipes. In addition to all of the common tasks required in populating a
data warehouse (for example, change data capture, slowly changing dimensions), readers will
also find valuable information on using ODI within a web service environment, and how to use
its powerful APIs to programmatically author ODI artifacts.

Since its acquisition, ODI has become the key bulk data technology within Oracle products
and within our cloud offerings. I hope you find it as impactful in your business as it has been
in ours.

Preface
After our collaboration on the ODI book Getting Started with Oracle Data Integrator 11g: A
Hands-on Tutorial, we thought that there might be a need for a more advanced book on the
same subject. So when Packt Publishing approached us to see if it would be possible to write
a Cookbook on ODI, we knew that we had the medium for this new adventure. Our objective
with this book was to avoid any repetition from the first book and to offer recipes that go
beyond what is readily available in the ODI documentation and on the Web. Hopefully, you
will agree that we have achieved our goal.

What this book covers
Chapter 1, Installation, Deployment, and Configuration, answers several deployment
questions that we have been asked by ODI users over time. A hands-on approach to these
topics allows the reader to learn the answers that we regularly give to our counterparts.
Chapter 2, Defining the Oracle Data Integrator Security, expands the descriptions available
in the ODI documentation with "how-to" examples by providing recipes to implement several
different aspects of ODI security.
Chapter 3, Advanced Topology, delves into Topology beyond the definition of servers and
schemas. These recipes will explore specific elements of Topology that are not typically
explored by the average ODI user: definition of new technologies and datatypes, use of
actions, and controlling case sensitivity.
Chapter 4, Using Variables, expands the use of variables by implementing them in ways not
often documented within the product, such as using variables in resource names and how
to best use variables as parameters.
Chapter 5, Knowledge Module Internals, will shed new light on what is possible with KMs,
explaining how substitution methods are processed by ODI and even experimenting with
Java code inside the KMs.

www.it-ebooks.info


Preface
Chapter 6, Inside Knowledge Modules – SCD and CDC, offers an opportunity to expand on
the concepts covered in the previous chapter by focusing on KMs that may not be well known
or well understood. We will also experiment with a few alterations of these KMs to provide an
even more hands-on experience.
Chapter 7, Advanced Coding Techniques, begins by looking into code generation that can
be performed directly from the models using diagrams. This chapter then explores specific
advanced topics such as temporary interfaces, embedded SQL queries, pivots, and partition

exchange loading.
Chapter 8, Package Loop and File Processing, was written because we noticed that too many
users limit their workflows by not knowing how to use them for more mature integration
techniques. The recipes in this chapter demonstrate some of the more sophisticated
integration techniques, including a focus on flat files processing that will help a developer
greater take advantage of ODI orchestration.
Chapter 9, XML and Web Services, discusses two areas of growing importance within ETL
processing: using XML files as input and using web services. Recipes will start with the basics
of the definition of an XML file and go all the way to invoking web services with callbacks.
Chapter 10, Advanced Coding Techniques Using the SDK, is rich in sample code that
automates tasks usually done with the graphical interface, including installation,
development, and execution monitoring.
Chapter 11, More with ODI, is a catch-all chapter that addresses questions we've often had
to answer, including misconceptions on how the product should be used, and little known
secrets that we didn't want to leave aside.

What you need for this book
Since Oracle is one of the leading database platforms, it has been used throughout this book
as the primary database technology. By using the DDL installation scripts available through
the publisher (see the following section, Downloading the example code), all of the required
source and target tables can be created and populated in two of the schemas referenced
throughout the book. Please note that should you choose to follow along using an alternative
technology and/or schema, you will most likely need to adjust the syntax and options
accordingly. The following scripts are available:
ff

CREATE_USER.sql: (creates the two cookbook demo user accounts)

ff

CREATE_SRC.sql: (creates the source tables)

ff

CREATE_TRG.sql: (creates the target tables)

ff

LOAD_SRC_SCHEMA.sql: (populates the source tables)

ff

LOAD_TRG_SCHEMA.sql: (populates the target tables)

2

www.it-ebooks.info


Preface
Some of the recipes within this book will also be referencing flat files, so it will be necessary to
establish a folder/directory within the reader's environment and to copy the available (*.txt)
files into this location. For example, create a directory location called C:\Temp and copy the
SRC_AGE_GROUP.txt and SRC_SALES_PERSON.txt files into that folder.
Once all the schemas have been created and the database schemas have been loaded, the
reader should start up ODI and perform the following preliminary tasks:
ff

On the Topology tab and within the File technology, create a physical data server,
physical schema, and logical schema for the DEMO_FILE schema. Note that the

physical location should be C:\TEMP.

ff

On the Topology tab and within the Oracle technology, create a physical data server,
physical schema, and logical schema for the DEMO_SRC schema.

ff

On the Topology tab and within the Oracle technology, create a physical data server,
physical schema, and logical schema for the DEMO_TRG schema.

ff

On the Designer tab, create a data model DEMO_FILE logical schema.
Import the SRC_AGE_GROUP data store using the available XML file.
Import the SRC_SALES_PERSON data store using the available XML file.

ff

On the Designer tab, create a data model and reverse engineer the DEMO_SRC
logical schema.

Who this book is for
This book has been designed to present the reader with solutions to specific problems that
sometimes challenge even the most accomplished ODI developer. As such, it is not meant to
teach the fundamentals of the ODI product, but rather to extend the reader's understanding
of Oracle Data Integrator's capabilities. In order to expedite the presentation of the material
within this book, there is an assumption that the reader already has a basic understanding
of the ODI product and has ready access to a database. For those readers looking for an
introduction to ODI, we recommend the book Getting Started with Oracle Data Integrator
11g: A Hands-on Tutorial by Packt publishing.
